Impressive out a of a 1" sensor! This is an example of what Sony have been shipping in their high end security camera line (based on the A7s 35mm sensor).

I will check  1152 this weekend with an IR Helium Neon Laser.  I'd be dreaming to see response at 1.35 or 1.5 um, but that would seriously make my day as a laser specialist.

Such longer wavelength are another topic than just getting the highest sensitivity with silicon.
Germanium photodiodes on silicon are supposed to replace InGaAs sensors as a more affordable solution.

frogg:
The Sony A7S line is well known among photographers as having incredible sensitivity.



Of course, the latest micro-channel plates have inherently better resolution and response time (and they are much more compact and the power requirements significantly lower), but the good thing about the A7S's is you can get them at Best Buy :)

Interesting finding for another camera using (maybe) Sony a7s sensor.

Canon also have ML-100 and ML-105 using (maybe) Canon ME20F-SH sensor.

Sensitivity to red light, in particular, is extremely high. I suspect also to near-IR. When set to 7.5fps and black & white it's possible to see around a room lit by one power-on neon. But those YouTube videos claiming performance equalling or exceeding Gen III are at best somewhat misleading.

I plan to do some tests in due course to try and relate its sensitivity to ISO figures on a 35mm camera. But it'll have to wait until I can get to some open countryside: there's too much local IR floodlighting to do a fair test.

Apologies for digging up a slightly older thread, but that would be an interesting comparison, particularly how the response varied between a full spectrum DSLR/MILC as you get into near-IR frequencies. Full-spectrum conversion companies have said their modified cameras are sensitive up to 1100nm, the Sionyx appears to be significantly better in this regard. This is the closest I've seen to a comparison between them:
